We are pleased to announce the release of a new webhook for delivery events in Postmark. This enhancement will allow customers to trigger additional actions on their end, such as updating user information, by feeding delivery events into internal systems. The new webhook also enables customers to provide delivery events directly to their customers through a custom UI, reducing complaints and queries about email delivery. Additionally, it allows for the aggregation of delivery events to calculate when there are delivery slowdowns and take action accordingly. The webhook will post a hook to the customer's specified URL with details such as recipient, tag, delivered timestamp, and response line from the destination email server. To help customers get started, we have put together a help article on setting up the delivery webhook.
